S614943-084 - Tube-Alloy 865-S MOD Metal Core Hardfacing Wire

Industrial Grade Hardfacing: Hobart Tube-Alloy 865-S MOD

Hobart's Tube-Alloy 865-S MOD is a high-performance tubular welding wire designed for the rigorous demands of the steel production industry. Supplied in a bulk 600 lb drum, this 1/8" (3.2mm) wire is intended for heavy-duty, automated hardfacing operations. The "MOD" designation indicates a modified stainless steel chemistry that has been tailored to solve specific wear problems encountered in continuous casting operations. Unlike standard stainless overlays, this alloy is engineered to provide the ultimate resistance to thermal fatigue and fire cracking, ensuring that rolls maintain their surface finish and structural integrity for longer periods.

Metal-cored wires like the Tube-Alloy 865-S MOD offer distinct advantages in production environments. They typically provide higher deposition rates and better deposition efficiency than solid wires or conventional flux-cored wires. This means more metal is deposited in less time, with less waste and cleanup. The gas-shielded arc is stable and produces minimal spatter, which is crucial when building up uniform layers on large cylindrical parts like caster rolls. The resulting deposit is not only resistant to thermal shock but also provides good corrosion resistance and stands up well to metal-to-metal wear, protecting the base material from the abrasive action of the steel slab.

This product is an essential consumable for maintenance and repair operations (MRO) within steel mills. By resurfacing worn rolls with Tube-Alloy 865-S MOD, facilities can reclaim expensive components rather than replacing them, driving down operational costs. The 600 lb drum packaging supports continuous welding operations, reducing the frequency of spool changes and maximizing arc-on time. Whether used for single-layer or multiple-layer overlays, this wire delivers consistent, high-quality results that meet the stringent standards of modern steel manufacturing.

Applications and Performance:

• Continuous Caster Rolls: The primary application, where resistance to fire cracking is paramount.
• Steel Mill Rolls: Suitable for various rolls subjected to heat and metal-to-metal wear.
• Corrosion Resistance: The modified stainless composition offers protection against corrosive elements in the mill environment.
